CHS: Cannabinoid Hyperemesis Syndrome
Cannabinoid Hyperemesis Syndrome (CHS) is a rare condition that has been associated with chronic, long term use of cannabis. Hyperemesis is a word used to describe intense vomiting.
Patients suffering from CHS experience periods of vomiting, nausea, and abdominal pain after consuming cannabis. It is thought Cannabinoid Hyperemesis Syndrome develops in those who consume large doses of cannabis over a long period, and the symptoms almost always abate once cannabis consumption ceases.
Is Cannabinoid Hyperemesis Syndrome common in medical cannabis patients?
No, CHS is a very rare condition that has only been discovered in a small percentage of people who take cannabis-based medicines. It is still being researched, but current estimates suggest that less than 1% of regular cannabis patients develop CHS.
How long does it take for symptoms of Cannabinoid Hyperemesis Syndrome to appear?
The development of CHS can vary from person to person, but it is usually seen in individuals who have been using recreational cannabis heavily for more than 10 years.
Does this mean medical cannabis is dangerous?
No, cannabis-based medicines have been shown to have a very high safety profile, especially when compared to some of the pharmaceutical options that cannabis can replace. CHS is an uncommon side effect that is only seen in a small fraction of people who take cannabis regularly.
